SDL_GL_SwapWindow (which wzScreenFlip calls) is basically a super-simple code-path that just triggers an OpenGL backbuffer / framebuffer swap... which immediately leads to the graphics driver. So the problem still looks to be in the NVIDIA drivers.

I just want to add that this was working so many years (from 2.x version to 3.1 I think, even on older drivers) I cleaned and installed/tested with a few older ones.. this is not a fault in drivers, only this game have problems , also last time when you guys wrote the same (nvidia driver fault - before even menu was shown) it was not true and game is fixed now, only that menu remaining I running: warzone2100-master-20180524-201429-0005774.exe 24-May-2018 18:39I have old graphic card (nvidia gt220) , but this is not an issue.. game is old and should run the same as old 2.3 version
